Disable/Enable network protocol discovery for NPM (BGP/OSPF/EIGRP/ISIS)

Products

• VMware Smart Assurance
• Network Observability

Issue/Introduction

• This article explains how one could enable and disable protocol based discovery on the AMPM domain towards the respective NPM domain managers.

• BGP topology not being discovered for devices in IP manager.

• BGP topology deleted post IP domain restart.

Environment

All supported Smarts versions

Resolution

• First check if return is TRUE of FALSE on DisableProtocolDiscovery

<Base_IP_Dir>/smarts/bin/dmctl -s <server name> invoke ICF_TopologyManager::ICF-TopologyManager findParameter DisableProtocolDiscovery

• To disable NPM discovery:

<Base_IP_Dir>/smarts/bin/dmctl -s <server name> invoke ICF_TopologyManager::ICF-TopologyManager insertParameter DisableProtocolDiscovery TRUE

• To enable NPM discovery:

<Base_IP_Dir>/smarts/bin/dmctl -s <server name> invoke ICF_TopologyManager::ICF-TopologyManager insertParameter DisableProtocolDiscovery FALSE

Note: Using a dmctl command means you do not have to restart the domain.

Additional Information

To make these changes permanent (retain settings post restart of AMPM domain):

• Edit the tpmgr-param.conf file using sm_edit as follows:

<Base_IP_Dir>/smarts/bin/sm_edit conf/discovery/tpmgr-param.conf

The following is the default:
#Enable/Disable protocol (pm) related discovery.
DisableProtocolDiscovery TRUE

• Set this to TRUE(to disable NPM discovery) or FALSE (to enable NPM discovery) based on the requirements.
  
  
• Restart the AMPM domain for the settings to take effect. 
  
  
• Post the restart of AMPM, run a 'discover all' on the IP domain.
